All cars have a wiring harness the cool thing is Tesla is moving to a 48v system for accessories and ditching the 12v system that has been used for over a century. Now with 48v architecture the wires used can be tiny reducing the weight a boatload and is much more efficient.
Resistance is proportional to cross section area and current. Power is current times voltage. So for same power delivery, 12 to 48 volts is 4 times the voltage so current can be one quarter of what it was, so for same resistance and same power loss we could use a quarter the cross section area of wire that would be half the thickness. But for thebsane length, we need only use onevquatlrter the weight of wire. Wire is coper and costs based on weight so one quarter thevwire cost. Not quite a boat load but close.
One peddle driving takes about 5 minutes to adjust to. My 16 year old son who now has his learners permit has no problem going back and forth between an ice vehicle and a Tesla, nor do I
Learning how EVs work is fascinating! The Toyota bZ4X is a perfect example of reliable, efficient, and environmentally friendly EV engineering designed for safe and smooth driving.
Great and detailed review. Best I have seen so far!Good job and hands up from a happy owner of the EX30 Ultra. You only forgot the speakers in the back, but that’s forgiven 😊

Nice course about EV. The company I'll work for as intern is making mobile charge for EVs. And now I understood better why this charge points are gonna be game changing

As a young boy 40 years ago I've had an electric toy car with a remote and instantly was amazed at how agile it was and how long the (non - rechargeable) batteries lasted. When I then saw the Roadster and Rimac with his converted green BMW my brain melted (metaphorically).
Very good video. The vast majority of charging is overnight at home or during the day at work if available. Modern public DC fast charging is mostly intended for road trips. Time to fast charge has improved and on average is 25 to 30 minutes to 80%. If people could fill up their ICE cars at home, how often would they go to a gas station unless they were going on an extended road trip?
@@Supraboyespersonally I take 40 seconds a month to charge my car. 10 seconds to connect, 10 to disconnect. Charge twice a month, charges while I sleep.
The world has evolved so much. 20 or 30 years back, one would have to pass a load of different exams to be accepted to a prestigeous brick - and- mortar University, get a life time student loan just to have access to a fraction of these same information that is now less than ¢50 to access from the comfort or your pocket and/from your toilet.
True! I used to spend hours in my school computer lab, after lecture., to just finish a project required to be uploaded for a score by my professor. Years later, i don't think today's college students that kind of pain! And, student loans never end! It's like being jailed for life 😂 No! Not really funny 😔
I'm only a few minutes into this video and it seems very informative, especially providing history and a timeline of the EVs. Before I consume this information, I'm thinking is there a breakdown on the impact of all these EVs on the power grid and truly where does this power come from. I need a detailed view of how the backend operates.
There should not be two potentiometers on the fuel pedal. There should be three potentiometers. That way the computer can determine which potentiometer is not properly working and take only the information from the other two potentiometers, but send a signal to the owner to visit the repair shop as soon as possible so that all potentiometers can be working. 😊
Thank you! It's always nice to hear such kind words. It is learners like you who remind us of the reason we love doing what we do. Thank you very much!
Using the original Leaf as an example, when driving in D mode regeneration happens when the break pedal is pressed, where as in B mode regeneration happen once the driver takes their foot off the accelerator @@Hlutea-Hmar
Braking could be defined as slowing the car or engaging the pads on the disks in disk braked cars or engaging the shoes on the drums on drum brake cars. Ice cars can be slowed (braked) by lifting your foot off the gas pedal, then the forward motion is slowed by forcing the motor to rotate without burning fuel. A manual and an automatic gear box means that slowing feels different. But in both cases is called engine braking. With an EV something similar happens but now the motor being forced to rotate turns the motor into a generator and the generated electricity can be put back into the battery. The amount to regenerated electricity stored back in the battery is under software control. As well as engine braking ice; regenerative braking EVs, conventional brakes can be applied by pressing on the brake pedal.
The main thing behind drive by wire is the cost of production. It is way cheaper and the price can be wracked up while production cost plummets. Although, at the same time safety is being compromise - but who cares. The share holders are happy and that's what counts.
Fun fact, ICE engines are 10-20% efficient with the energy they consume meaning the rest is wasted in the form of vibration, sound, & emissions. But an Electric Motor is over 90% efficient with it’s energy. This is why charging an EV from a gas generator is still greener than a gas powered car, albeit the worst/most expensive way to charge. I get having an ICE toy & making noise, but it’s literally the sound of innefficiency. Some make them even more loud and therefore inefficient for extra power while everyone’s ears and lungs suffer.

Of course there is very little CO2 in the atmosphere, see NASA, ~20% O2, ~78% N, ~0.9% Ar, & ~0.045% CO2. CO2 a rare, colourless, odourless, tasteless gas essential for humans, flora and flora. Low CO2 (< 0.02% CO2) causes poor flora growth, greenhouse plant/vegetable growers add up to 0.10% CO2 for better plant results. No CO2 causes death to humans, flora and flora. Love to have an electric car but currently they do not make sense. CO2 reduction is a total scam, we should actually add more to the atmosphere if possible. Look forward to increased electricity costs and blackouts from crazy politicians and incompetent or corrupt "scientists". A distraction from insane politician. Show us the proof!!

Although, charging times are continuing to decrease, the perception of charging versus gasoline needs to be changed. The average person drives roughly 40miles a day. Every night the EV can be charged at a much reduced cost. Most people don’t have gas pumps at home. People also tend to forget that gas pumps don’t work when the grid is down. Battery storage and solar/wind can keep the storage systems charged and available regardless of the grid. In other words, we can create electricity ourselves. Most of us can’t refine gasoline if needed. Then there’s the benefit of powering your house from the EV during an outage.
Except the poor army of people that not have off street parking. How are these people going to keep mobile in your brave new utopia if cannot access the few working public chargers at unsafe times of the night. People not stealing fuel pump pipes as areas well camered but unfortunately with limited security is nothing to stop theft of charge cables.
In general, very good presentation, IMO. However, at 2:23:26 where you are describing autonomous features your graphic shows a slower moving vehicle overtaking several faster moving vehicles several times. A second graphic relating to the suspension system operation also portrays inaccuracies. At 2:41:06, as you move over a speed bump, it shows the tie rod end disconnecting from the steering knuckle and the lower ball joint disconnecting from the suspension component it is supporting. The upper A frame is behaving properly. The explanation of sprung and unsprung weight(mass) was introduced correctly but it didn’t explain why it mattered - you did mention that F=MA but you didn’t connect that to unsprung weight.
11:19 That’s not really true these days. Heat is not wasted, a lot of times it’s used by the cars heat pump to generate heat for the cabin. In fact some Teslas use 16 sources of what would be wasted heat for their heat pump to warm the cabin. These 16 sources of heat come from everything from the batteries to the traction motors to all sorts of other components that generate heat including the liquid cooled computer. It’s pretty impressive what Tesla has done with their heat pumps. That heat is no longer wasted, it goes into the cabin when needed of course
Anyone who's driven an electric car knows there’s no going back to gas. No comparison and being much more efficient is a bonus. Getting about 300 miles for just $7 of electricity
Totally agree especially with Teslas. My opinion changed after my son bought his 2024 Model 3 and ordered one. Aside from mx and fuel savings, the responsive and performance is what changed my mind.
So shout out to the following celebrities that I’ve seen driving a Tesla, and when I say that I’ve seen them driving a Tesla I’m not talking about actually seeing them in the flesh, but on RUclips or other social media platforms, celebrities like Kim Kardashian who was recently spotted driving the CyberTruck, Jamie Foxx, driving a Tesla M/3 on some guys RUclips channel, Harrison Ford, and Ben Affleck, seen driving the M/S in a paparazzi photo, but I’ve yet to see any of these people actually come out, and make a statement, saying hey guys, you gotta go out and buy one of these electric cars, because not only will you save money, but you’d also be doing your part in helping to save our planet. Yeah, I know, Legacy auto manufacturers pay these guys a lot of money to just sit in their cars without even requiring them to actually drive them, but I’m not gonna go out and buy a Lincoln just because Matthew McConaughey or Serena Williams sits in a Lincoln.
@@valleyofiron125 I was referring to the lead acid batteries that all EV's have in addition to their main li battery. A few years ago Tesla switched that additional lead acid out for a small li battery.
Hi, thank you for your video. Is it possible to download your video and use it for educational purpose in France ? We would translate it. Thanks. Regards.
They can't because they have to be in separate blocks so that the cooling fluid can circulate around and a giant battery can't just have one set of positive and negative contacts,very dangerous!🤔
Because trains/trams are not BEVs which is the typical meaning of EV or electric vehicle. As there are exactly zero capacitor EVs on the market today, they're quite irrelevant for the same reason nuclear powered cars are. Additionally, hydrogen fuel cell vehicles are definitely not EVs with 96% of hydrogen being made by fossil fuels, not renewably. Hydrogen is consumed in the process being converted to H2O vapor "exhaust" which is a greenhousegas Btw. Like most hybrids, they can't be plugged in, forcing owners to depend on one of a couple dozen H2 stations in the entire nation making them impractical for almost everyone. Can't fill up at home either like most EVs do.
EV's are usually charged at home, plugged in just like your phone over night. Charging stations are only used for long trips and the few who own them that don't have their own home
How electric vehicles work compared to gasoline/petrol powered internal combustion engines: in los angeles, california, we pay just over five dollars for one gallon of gasoline. because of the extreme inefficiency of even the best, mass produced internal combustion engines, four dollars goes to making heat, and one dollar moves the automobile. with an electric vehicle, if we spend five dollars on electricity, 4 dollars and 90 cents goes into moving the vehicle, and ten cents goes to making heat. it’s interesting to consider the popularity of the transition to the efficiency of electric vehicles. everyone loves efficiency. and when it comes to combustion, those engines are heaters first. and they move a little, comparatively.
16:23 Ehhhh EVs have a generally lower maintenance powertrain but their low voltage wiring and other areas of QA have been lacking. Also, an ICE will have the same range it did at 300k as it did new. BEVs will total themselves if they need a new battery
Also, on a trip if you stop and charge every couple of hours it will only take you 10 to 15 minutes to charge which is not long enough to go to the bathroom and stretch your legs. Let alone get something to eat. You end up running out to move your car so you don't get charged idle fees.
800 volt architecture is not required, it simply has a couple of advantages like allowing for faster charging. If you look at electric lawn mowers, Greenworks has complete lines of tools that use different voltages like their 40v line and their 80v line. All similar tools just made with different voltages because, well, to put it simply, MARKETING!
Higher voltages propellant systems aren't for "marketing", at all. Increasing voltage reduces current, thus resistive losses. The less current that there is, the lower gauge wiring can be.
Li ion batteries were supposed to have no problems, then we found out they would developer dendrites when they are fully charged all the time and Tesla recommends keeping the charge between 20% and 80% for daily use and even Samsung has a setting on their phones that you can enable to stop charging at 85%
I will never understand why people keep claiming that EV's use some huge amount of electricity to charge, this is ludicrous. Take a look at your next electricity bill. It tells you how much electricity in kw you use per month. Then take into account that the average EV battery is 50kw to 75kw
Wrong, there are different levels of charging because it's better for your battery to charge slowly and superchargers near restaurants or malls typically run slower to give people more time to shop or eat. Tesla Supercharger are typically 250kw but ones near malls and restaurants are 75kw
No chapter on where the electricity at the charging socket comes from. This omission is misleading. On average it is generated, using energy, 80% from burning fossil fuel at a distant power station.
If the EV can give back power to the grid during a time when demand is high, then does that mean you can plug your EV into a charger and actually lose charge?
Wrong again, Tesla developed an eco friendly method of mining that leaves the area the same (minus the lithium) and a new eco friendly method of refining the lithium, they already broke ground on their lithium refining plant in Texas.
It is December 2023 as i write. This video was made a year ago.. EV's have now been proved to be not as the propaganda of a year ago showed them. Selling figures are so low that their production in most major producing companies has now stopped.
as a battery technician for 14 years i can only say you need to learn more about lead acid vrla batteries, they are NOT gel batteries, they are absorbent glass mat batteries, the electrolyte is absorbed in a special "sponge" it is not gelificated in any way, you can turn a gel battery upside down and work with it no problem, you can't do that with a vrla battery, anything that is more than 45º angle will eventually damage the battery, saying the lead acid battery has low power density is also a stupidity, try to put a nickel metal hydride battery starting an engine vs a lead acid battery and see how many start cycles you will get out of them, i assure you lead acid will do tons more starting cycles before it gets depleted.
The only maintenance on a Tesla is tires and wiper fluid. Oh wait, because of regen braking, you might have to replace the brakes every 200,000 to 500,000 miles
Did you mention tires that are more expensive and wear out faster? How about insurance companies that show their love. Finally a small fender bender can total an electric car.
Ice cars have to run between certain temperatures as well. They won't run when extremely cold or hot environments because of overheating or freezing fuel and ice vehicles do not have a thermal management system

can you please specify more about the lighting loads ,compressors,lamps, horns,sensor that are being used and thier connections and their operations
Although, charging times are continuing to decrease, the perception of charging versus gasoline needs to be changed. The average person drives roughly 40miles a day. Every night the EV can be charged at a much reduced cost. Most people don’t have gas pumps at home. People also tend to forget that gas pumps don’t work when the grid is down. Battery storage and solar/wind can keep the storage systems charged and available regardless of the grid. In other words, we can create electricity ourselves. Most of us can’t refine gasoline if needed. Then there’s the benefit of powering your house from the EV during an outage.
Except the poor army of people that not have off street parking. How are these people going to keep mobile in your brave new utopia if cannot access the few working public chargers at unsafe times of the night. People not stealing fuel pump pipes as areas well camered but unfortunately with limited security is nothing to stop theft of charge cables.
Hi,1 year down we have BYD charging CATL batteries 🔋 take 11mins to charge 0-80%.
In general, very good presentation, IMO. However, at 2:23:26 where you are describing autonomous features your graphic shows a slower moving vehicle overtaking several faster moving vehicles several times. A second graphic relating to the suspension system operation also portrays inaccuracies. At 2:41:06, as you move over a speed bump, it shows the tie rod end disconnecting from the steering knuckle and the lower ball joint disconnecting from the suspension component it is supporting. The upper A frame is behaving properly. The explanation of sprung and unsprung weight(mass) was introduced correctly but it didn’t explain why it mattered - you did mention that F=MA but you didn’t connect that to unsprung weight.
How does the heat management system heat the battery up in low temps? you mention how it cools it but not much info on heating it.
Great video thanks 😊
We hope you have an amazing experience & learn lots of exciting stuff! :)
11:19 That’s not really true these days. Heat is not wasted, a lot of times it’s used by the cars heat pump to generate heat for the cabin. In fact some Teslas use 16 sources of what would be wasted heat for their heat pump to warm the cabin. These 16 sources of heat come from everything from the batteries to the traction motors to all sorts of other components that generate heat including the liquid cooled computer. It’s pretty impressive what Tesla has done with their heat pumps. That heat is no longer wasted, it goes into the cabin when needed of course
Anyone who's driven an electric car knows there’s no going back to gas. No comparison and being much more efficient is a bonus. Getting about 300 miles for just $7 of electricity
Totally agree especially with Teslas. My opinion changed after my son bought his 2024 Model 3 and ordered one. Aside from mx and fuel savings, the responsive and performance is what changed my mind.
So shout out to the following celebrities that I’ve seen driving a Tesla, and when I say that I’ve seen them driving a Tesla I’m not talking about actually seeing them in the flesh, but on RUclips or other social media platforms, celebrities like Kim Kardashian who was recently spotted driving the CyberTruck, Jamie Foxx, driving a Tesla M/3 on some guys RUclips channel, Harrison Ford, and Ben Affleck, seen driving the M/S in a paparazzi photo, but I’ve yet to see any of these people actually come out, and make a statement, saying hey guys, you gotta go out and buy one of these electric cars, because not only will you save money, but you’d also be doing your part in helping to save our planet.
Yeah, I know, Legacy auto manufacturers pay these guys a lot of money to just sit in their cars without even requiring them to actually drive them, but I’m not gonna go out and buy a Lincoln just because Matthew McConaughey or Serena Williams sits in a Lincoln.
This guy just pulled this figure out of his behind!
No doubt from the side of the road somewhere while waiting for a tow truck!
don't get too comfortable because that's now, for example, look at califoniar they will fine the way to make you pay.

Tesla doesn't use lead acid any more, they were replaced with Li batteries over a couple of years now
@@valleyofiron125 I was referring to the lead acid batteries that all EV's have in addition to their main li battery. A few years ago Tesla switched that additional lead acid out for a small li battery.
Great video
Thank you for your feedback. You made our day!
Sir very helpful 🙂hindi lecture request 🙏🙏
Thank you for your feedback. You made our day! We always look forward to continuing serving you well :)
Race cars like Indy or formula one actually increase wind resistance to force the car downward to keep it from flying off the track at high speeds
Hi, thank you for your video. Is it possible to download your video and use it for educational purpose in France ? We would translate it. Thanks. Regards.
Good job 👏👏👏
Thank you! What a nice thing to say. We are so grateful to have a passionate learner like you as a part of the student community.
Should they design a single large battery instead of a too many batteries in the EV compartment?
They can't because they have to be in separate blocks so that the cooling fluid can circulate around and a giant battery can't just have one set of positive and negative contacts,very dangerous!🤔
Why no mention of common aerial commutator or ground rail EVs (as in trams and trolley buses), super-condenser/capacitor EVs, or Hydrogen Cell EVs?
Because trains/trams are not BEVs which is the typical meaning of EV or electric vehicle. As there are exactly zero capacitor EVs on the market today, they're quite irrelevant for the same reason nuclear powered cars are.
Additionally, hydrogen fuel cell vehicles are definitely not EVs with 96% of hydrogen being made by fossil fuels, not renewably. Hydrogen is consumed in the process being converted to H2O vapor "exhaust" which is a greenhousegas Btw.
Like most hybrids, they can't be plugged in, forcing owners to depend on one of a couple dozen H2 stations in the entire nation making them impractical for almost everyone. Can't fill up at home either like most EVs do.
Thank you sir ❤
Most welcome
Great 👏👏👏
EV's are usually charged at home, plugged in just like your phone over night. Charging stations are only used for long trips and the few who own them that don't have their own home
Yes because everyone owns a home … in LaLa land 😂
@@SME5724 I said "usually are" are you really that illiterate? And you don't have to own the home to charge.
Nice video ..Thanks for shearing

We all heard about firemen needs to dig a hole to bury the ecar to stop the battery flame.
How electric vehicles work compared to gasoline/petrol powered internal combustion engines:
in los angeles, california, we pay just over five dollars for one gallon of gasoline. because of the extreme inefficiency of even the best, mass produced internal combustion engines, four dollars goes to making heat, and one dollar moves the automobile.
with an electric vehicle, if we spend five dollars on electricity, 4 dollars and 90 cents goes into moving the vehicle, and ten cents goes to making heat.
it’s interesting to consider the popularity of the transition to the efficiency of electric vehicles.
everyone loves efficiency. and when it comes to combustion, those engines are heaters first. and they move a little, comparatively.
Have you considerd how the electricity is made .
16:23 Ehhhh EVs have a generally lower maintenance powertrain but their low voltage wiring and other areas of QA have been lacking. Also, an ICE will have the same range it did at 300k as it did new. BEVs will total themselves if they need a new battery
12:30
All internal combustion engines release harmful hydrocarbon gasses? What about Hydrogen fueled IC engines?
Bangor, Bangor
Also, on a trip if you stop and charge every couple of hours it will only take you 10 to 15 minutes to charge which is not long enough to go to the bathroom and stretch your legs. Let alone get something to eat. You end up running out to move your car so you don't get charged idle fees.
800 volt architecture is not required, it simply has a couple of advantages like allowing for faster charging. If you look at electric lawn mowers, Greenworks has complete lines of tools that use different voltages like their 40v line and their 80v line. All similar tools just made with different voltages because, well, to put it simply, MARKETING!
Higher voltages propellant systems aren't for "marketing", at all. Increasing voltage reduces current, thus resistive losses. The less current that there is, the lower gauge wiring can be.
Wer no 1 ev manufacturer BYD mentioned?
Because model Y was the biggest selling car last year including ICE cars
Li ion batteries were supposed to have no problems, then we found out they would developer dendrites when they are fully charged all the time and Tesla recommends keeping the charge between 20% and 80% for daily use and even Samsung has a setting on their phones that you can enable to stop charging at 85%
aahh! not just heat from charging to 100% i though stuff sulfate and what not at low charges, i did not know of dendrites at full charge!!!!
I will never understand why people keep claiming that EV's use some huge amount of electricity to charge, this is ludicrous. Take a look at your next electricity bill. It tells you how much electricity in kw you use per month. Then take into account that the average EV battery is 50kw to 75kw
15% lost in L2 charging. And California PGE charge $0.66/kWh
@TheEelnoraa Ya and in Montana, which uses hydroelectric, it's .06 per kwh and 15% lost, how do you figure? You incorrect sir.
@@TwilightKid I never said everyone pays $0.66. But California PGE customers do. We pay 11x more than you. No correct or incorrect, just facts.
You mean kwhr.
Wrong, there are different levels of charging because it's better for your battery to charge slowly and superchargers near restaurants or malls typically run slower to give people more time to shop or eat. Tesla Supercharger are typically 250kw but ones near malls and restaurants are 75kw
Sit down bub
What software was used to create the animations?
超級棒~ 感謝 很大的幫助
While I already knew most of this, it was still nice to play in the background while doing housework.
Exactly
same 😅
No chapter on where the electricity at the charging socket comes from. This omission is misleading. On average it is generated, using energy, 80% from burning fossil fuel at a distant power station.
Were you able to get the certificate?
60% in the USA. Irrelevant in any case.
Mine comes from Solar panels. 🤷♂️
Why is the Tesla charged with the CCS connector?
If the EV can give back power to the grid during a time when demand is high, then does that mean you can plug your EV into a charger and actually lose charge?
Wrong again, Tesla developed an eco friendly method of mining that leaves the area the same (minus the lithium) and a new eco friendly method of refining the lithium, they already broke ground on their lithium refining plant in Texas.
Other than charging the batteries, what rots or rust first if you don't use your EV for, say, a year?
The resale value is the first thing to rot or rust.
It is December 2023 as i write. This video was made a year ago.. EV's have now been proved to be not as the propaganda of a year ago showed them. Selling figures are so low that their production in most major producing companies has now stopped.
Amezing
as a battery technician for 14 years i can only say you need to learn more about lead acid vrla batteries, they are NOT gel batteries, they are absorbent glass mat batteries, the electrolyte is absorbed in a special "sponge" it is not gelificated in any way, you can turn a gel battery upside down and work with it no problem, you can't do that with a vrla battery, anything that is more than 45º angle will eventually damage the battery, saying the lead acid battery has low power density is also a stupidity, try to put a nickel metal hydride battery starting an engine vs a lead acid battery and see how many start cycles you will get out of them, i assure you lead acid will do tons more starting cycles before it gets depleted.
Hlo bro is it possible to connect with u
The only maintenance on a Tesla is tires and wiper fluid. Oh wait, because of regen braking, you might have to replace the brakes every 200,000 to 500,000 miles
Did you mention tires that are more expensive and wear out faster? How about insurance companies that show their love. Finally a small fender bender can total an electric car.
It wasn't short range and high cost, Ford's wife drove an electric vehicle and the bill on maintence for the year was one nickle
Ice cars have to run between certain temperatures as well. They won't run when extremely cold or hot environments because of overheating or freezing fuel and ice vehicles do not have a thermal management system
